Two Way Switched Lighting Circuits 1
Light switch two black one red. Or it could be the red wire is the wire going to the fixture and the black wires are the live wires. You will have to get a 4 way switch for that position not a 3 way switch. It could be there is or once was a three way switch in play. Well cover the easier scenario first.

After some help if possible. This is an older house circa 1967 and the wiring appears to be all over the place. The positive wire on a multimeter is red and the black wire is negative. 12 awg for 20 amp circuits and 14 awg for 10 and 15 amp circuits. Red and black form the same cable will connect ot he brass screws then the red and black from the other cable will connect ot he black screws. Thinking about it it may have been 2 blacks and 1 red but either way there are only the two colours.
They should both be of the same wire gauge. Youll have two cables in the switch box a live one with a black and white wire and the one going to the outlet which has a red black and white wire. There are two black wires attached to one brass screw and a red wire attached to the other brass screw. Twist the two red wires together and attach a wire nut. Dont get confused about using the red wire from the multimeter to test a hot black wire. Take the white wire from switch two and twist it with the black wire from switch one.
First twist the two bare copper ground wires together. When you see a red wire in a light switch box it can mean two things. Place the prong of the multimeters red wire on the bare metal on the end of one of the black wires. There appear to be two white assume neutral wires screwed together with a wire nut and a ground wire tucked away inside the junction box. 4 way switches have 4 screws 2 will be black and 2 will be brass.
